PVLANs

naive.naive · ‎07-08-2008

Hi,

I've the below scenario, and just wondering can it be done :

3 VLANs, VLAN A (10.1.1.0/24), VLAN B (10.1.2.0/24) and VLAN C (10.1.3.0/24), with the limitations :

- VLAN B & VLAN C can communicate to VLAN A and vice-versa

- members in VLAN B and VLAN C cannot communicate with each other

- each VLAN will have L3 ip address as above

I know PVLAN can performed on first 2 points, but I can't find anthing on the last point, where I can define L3 ip address for all the 3 VLANS.

Thanks..

What is the platform you intened to deply this on?

naive.naive · ‎07-08-2008

catalyst 3750

metro??

naive.naive · ‎07-08-2008

nope..normal 3750 switch..but does it matter ?

andrew.prince · ‎07-08-2008

Yes it does - as far as I know/remember you can have only one vlan with a layer 3 IP address, normally used for management. The metro version is a layer2 switch and layer3 combined. What is your exact model??

it a WS-C3750G-48TS-S, it's a L3 switch..

Yep - you should be good to go on giving each VLAN a SVI & IP address.

HTH.

Would an access list be a solution to this scenario also?
